Once the keg kicks, I rinse it a couple times with hot water. Then I fill about 1/2 way with hot water and oxyclean, seal it back up, and shake the hell out of it. I then force some oxyclean solution through my line ( cobra taps ) and leave some in there to soak. I'll let the keg soak for a few hours, then flip it so the top gets a soak for a few hours ( or days if I forget ). Finally, empty the solution and rinse several times before sanitizing and refilling.

Once they're empty, I sanitize them and refill. I fill them with star san, pressurize, and blow some out the dip tube to make sure it gets sanitized.

I replace the lines when they look a bit gross. I rinse them when I change kegs. I don't really get too crazy about the lines. Maybe I should. I'm using picnic taps, so I don't have a tower and faucets to worry about.

Rinse with hot water. Scrub with DEDICATED and sanitized toilet brush if anything caked in the bottom. Rinse again. Force water through the "OUT" connection (pressurized air on the "IN") Fill with about 6" of sanitizer, shake, force some out the connector, and store.......

I guess I'm the slacker here. As kegs die, I'll put them aside until I have 3 or 4 to clean. Then I make a strong PBW solution in 180F water and fill the first keg. Depress the poppet so the dip tube fills up I let it sit 30 minutes and push it with CO2 through a jumper hose to the next keg. I then rinse the first keg with hot water and repeat until all kegs are clean. Then I put about 3 gallons of 180F water in the first keg and push it through all the kegs to make sure all the kegs are rinsed, including the dip tubes. Once they're clean I leave them upside down over night to drain, put the lids back on and pressurize. I haven't changed o-rings on my kegs since I first got them, some of them have been in use 14 years now.About every 2 months I use a line cleaning solution and pump a couple of gallons through each tap. ishould do it more often but I don't.

I rinse the gunk out first. Sprinkle a little oxyclean in and add about a quart of hot water. Shake the crap out of the keg. Drain and rinse until oxyclean-free. Disassemble and rinse the posts/poppits and run a swab through the dip-tube. Sanitize. Reseal and it is ready to go.

Every now and then I run an oxyclean and boiling water solution through the lines. I still have the same lines that I bought in spring 2007.

I fill the keg up with hot tap water then add a 1/2 cup of OxiClean and place the lid on. Push both poppets to make sure some solution shoots up the tubes and leave it for two days. OxiClean can't do its job if it's put in and quickly rinsed out . .it needs time to scour. Rinse thoroughly with hot water both tank and tubes and rack new beer in. Been doing it this way for 7 years without issue.

I agree Oxiclean takes time, but I find 2-3 hours is plenty of time for it to work. Also, I use less that 1/2 as much as you do. Maybe 2-3 Tbsp. per 5 gal. keg or fermenter.

My two day time line is more a matter of convience of getting back to finish the process . . . I agree 2 to 3 hours (at least as far as the carboys I occasionally use) has every trace of the sticky junk line scrubbed clean. The stuff will continue to release its O2 for quite awhile. I'd be afraid to be so frugal as to only put in 2-3 Tbsp, but I have been known to overkill on more than one occasion!
